Amazon Prime Day is upon us, which means a limited time to score great deals on all that Amazon has to offer.

First, here’s what you need to know about Prime Day

30 hours to shop

The third annual Prime Day will actually run a bit longer than 24 hours this year.

It kicks off at 9 p.m. ET on July 10 and runs until 3 a.m. ET on July 12. Amazon says new deals will be offered every five minutes.

Prime members with an Amazon Echo, Echo Dot, Echo Show, Amazon Tap, compatible Fire TV or Fire tablet can start their Prime Day shopping even earlier. Beginning at 7 p.m. ET today, July 10, voice shoppers will have exclusive early access to select Prime Day deals. Learn more by visiting www.amazon.com/alexadeals.

Customers who don’t already have Prime memberships can sign up now take advantage of this year’s deals. Prime costs $99 per year, or you can also sign a 3o-day free trial.

Note: Many deals are only available for a limited time. We will try to keep the page updated, but always double check the price on Amazon.
